这不会发生在任何 iPad 设备上，只有 iPhone 设备才会发生.
This doesn't happen on any iPad devices only iPhone ones.
即使在更瘦"的应用程序上尝试过，仍然发出同样的警告，我正在使用 UIWebView 的加载请求:
Even tried it on a "skinnier" application still same warning and I'm using the load request of the UIWebView in :
dispatch_async(dispatch_get_main_queue(), ^{
NSString *rec = [_m3u8 string"];
NSURL *url = [NSURL URLWithString:rec];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
self.WebView.allowsInlineMediaPlayback = YES;
[self.WebView loadRequest:request];
});
感谢任何提供帮助的人.
Thanks to anyone who helps.
推荐答案
UIWebView 仍然没有多大成功，但是有一个名为WKWebView"的对象是
Well still not much success with UIWebView however there is an object called "WKWebView" that is a part of <WebKit/WebKit.h> to implement :
#import <WebKit/WebKit.h>
然后在您的 viewDidLoad 等中初始化:
Then to init in your viewDidLoad etc :
WKWebView *w = [[WKWebView alloc]initWithFrame:self.view.bounds];
NSURL *url = [NSURL URLWithString:@"yourLink.m3u8"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[w loadRequest:request];
[self.view addSubview:w];
再向您的 .plist 文件添加一件事:
One more thing add to your .plist file :
应用传输安全设置 - 字典.
App Transport Security Settings - Dictionary.
允许任意加载 = YES.
Allow arbitrary loads = YES.
它比 UIWebView 快得多，而且我没有在日志中收到上面提到的警告.
Its much faster then UIWebView and i don't get the warning mentioned above in the log.
干杯.
